LIFTED LAMINAR JET DIFFUSION FLAMES [PDF]

open access: yesCombustion Science and Technology, 2005
This paper addresses the numerical description of lifted flames in axisymmetric laminar coflow jets. The analysis considers moderately large values of the Reynolds number, when the boundary-layer approximation can be used to describe the slender mixing region that extends between the jet exit and the flame, providing the profiles of velocity and ...

Simultaneous measurements of flame geometry and flow field by OH-PLIF/Stereo PIV

open access: yesNihon Kikai Gakkai ronbunshu, 2016
It is difficult to understand turbulent combustion, because the combustion process is very complex and unsteady. One of the useful parameters for discussion of the unsteady flame behaviors is the flame stretch rate, which is evaluated by local flame ...

Unsteady flamelet modeling for N2H4/N2O4 flame accompanied by hypergolic ignition and thermal decomposition

open access: yesApplications in Energy and Combustion Science, 2021
In this study, the applicability of the flamelet approach to numerical simulations of hydrazine (N2H4)/nitrogen tetroxide (NTO, N2O4) combustion, in which hypergolic ignition and thermal decomposition occur, is investigated in terms of two-dimensional ...

Flame Structure of a Jet Flame with Penetration of Side Micro-jets [PDF]

open access: yesChinese Journal of Chemical Engineering, 2008
Abstract In this paper, an innovative jet lifted flame with side micro-jets has been proposed and its effects on the flame structure have also been investigated. Due to the changes of the initial combustion conditions, mixing and aerodynamics which resulted from the perturbation of the side micro-jets, such a lifted jet flame has different flame ...

Experimental Study on Bluff-Body Stabilized Premixed Flame with a Central Air/Fuel Jet

open access: yesEnergies, 2017
Bluff-body flame holders are commonly employed in many industrial applications. A bluff-body is usually adopted to enhance the downstream mixing of the combustion products and the fresh fuel-air mixtures, thus to improve the flame stability and to ...
